High School DXD, High School of the Dead, Higurashi (which I've seen classified as hentai for whatever reason), Valkyrie Drive, Senran Kagura and Game of Thrones all have profiles here. All feature heavy fanservice style content. Game of Thrones and The Boys have multiple profiles despite featuring egregious and frankly disgusting sexual content.
It also parodies isekai manga and harem manga, with several minor characters being isekai heroes with multiple women chasing them, including one such woman who tries to hide the fact that she's glad when Sa-Me eats her love rival, at least until he eats her too. The isekai harem guy is even shown being cocky about his invincible power and how he can always beat everything, only for Sa-Me to kill him easily. And the manga parodies shark creature films too, since after Jaws lots of films were made inspired by the concept, and the number of them that were actually good was about five or six, at most, and keep in mind I'm counting The Meg and Deep Blue Sea among the good ones, and they were hardly as good as Jaws.
